Definitions

  • the invention relates to a manual switching valve for an automatic transmission of motor vehicles, the type explained in the preamble of patent claims 1.
  • DE 20 26 087 B2 discloses a switching device for an automatically switching Motor vehicle change transmission is known in which an actuatable by a selector lever Generic manual control valve in the usual for an automatic transmission of a motor vehicle Operating positions P, R, N, D1, D2 and L can be moved to one Pressure medium inlet pressure corresponding to the pressure medium outlets to be distributed according to the selected operating area.
  • the object of the invention is to provide a manual switching valve for an automatic transmission of motor vehicles of the type explained in the preamble of claim 1 to improve that an undesirable loss of pressure medium from the clutch valve to the manual valve and thus to the hydraulic clutches is avoided and accordingly an accelerated switchover from the operating position P to reverse gear or to forward gear without annoying application delay and is made possible without disruptive impulses.
  • this object is achieved by a manual valve for a automatic transmission of motor vehicles in the preamble of the claim 1 explained type shown in the characterizing part of claim 1 Features.
  • valve element at its positions D and L controls End is provided with an extended control collar, which has two radial holes has an axial connecting bore and a shoulder, such that in position P the extended control collar blocks the pressure medium inlet, the second radial bore is also blocked by the valve bore, so that when the Motor vehicle an empty line between the clutch valve and manual valve by venting via the pressure medium inlet which is depressurized when the engine is not running is avoided, at position R, the pressure medium outlet D via the second radial Bore and the paragraph is vented, in position N the pressure medium outlets D and L are vented through the three holes and the heel, in position D the Pressure medium outlet L is vented through the three holes and in position L the extended one
  • the tax authority has no influence on the pressure medium build-up prevented this channel.
  • the conventional manual switching valve shown in Fig. 2 is schematic in the drawing shown and consists essentially of a valve body 1 with a valve bore 2 and a valve element 3 with two control collars 4 and 5.
  • the pressure medium inlet is designated IN, while the pressure medium outlets for the different operating ranges R, D and L are designated.
  • valve element 3 As can be seen from Fig. 1 in the illustration in the position P, is according to the invention the valve element 3 with an extended control collar 6 with 2 radial bores 7 and 8 and an outwardly closed axial bore 9 as well as with a paragraph 10.
  • valve element 3 results in its valve bore 2, the extended leads Steuerbund 6 for the following functional changes:
  • the extended control collar 6 covers both the pressure medium inlet IN and does not allow venting because the second radial bore 8 still is covered in the area of the valve bore 2. This is a venting of the pressure medium supply from the clutch valve to the manual valve.
  • both the pressure medium outlet D and the pressure medium outlet are L vented through the three bores 7, 8 and 9 and the pressure medium inlet IN sealed off by valve collars 4 and 5.

Claims (1)

  1. Valve manuelle pour une transmission automatique de véhicules automobiles, comprenant un élément de valve (3) déplaçable dans un alésage de valve (2), qui est actionnable par un levier de sélection, une entrée de fluide sous pression (IN) et plusieurs sorties de fluide sous pression (R, D et L) étant disposées dans l'alésage de valve (2) et l'élément de valve (3) présentant plusieurs épaulements de commande (4 et 5) par le biais desquels il répartit le fluide sous pression présent dans les diverses positions de fonctionnement (P, R, N, D et L) au niveau de l'entrée de fluide sous pression (IN) sur les diverses sorties de fluide sous pression (R, D et L) ou purge celui-ci,
    caractérisée en ce que
    l'élément de valve (3) est pourvu, dans le logement de valve (1) à proximité de l'épaulement de commande (5) sur son extrémité contrôlant les positions (D) et (L), d'un épaulement de commande (6) prolongé qui présente deux alésages radiaux (7 et 8) et un alésage axial (9) reliant ceux-ci ainsi qu'un retrait (10), de telle sorte que dans la position (P), l'épaulement de commande (6) prolongé bloque l'entrée du fluide sous pression (IN) qui est sans pression lorsque le moteur est au repos, le deuxième alésage radial (8) étant également bloqué par l'alésage de valve (2), de sorte qu'à l'arrêt du véhicule automobile, une marche à vide des conduites entre la valve d'accouplement et la valve manuelle soit évitée par une purge par l'entré de fluide sous pression (IN) sans pression lorsque le moteur est au repos, dans la position (R) la sortie de fluide de pression (D) soit purgée par le deuxième alésage radial (8) et le retrait (10), dans la position (N), les sorties de fluide sous pression (D) et (L) soient purgées par les trois alésages (7, 8, 9) et le retrait (10), dans la position (D), la sortie de fluide sous pression (L) soit purgée par les trois alésages (7, 8, 9) et dans la position (L) l'épaulement de commande (6) prolongé n'ait aucune influence sur l'accumulation du fluide sous pression.
